IPC: C10L9/00
Filed: 1981-12-15
Abstract: PURPOSE:To increase the recovery rate of coal, by mixing an emulsion oil with a coal/water slurry and repeating an ultrasonic irradiation stage, a gas-introducing stage and a separation stage in the deashing of coal by an oil addition/ granulation method. CONSTITUTION:Coal is coarsely crushed 1, and finely divided 2. A coal/water slurry is prepd. in a slurry preparation tank 3 and fed to a mixing tank 10. An emulsion oil 8 is prepd. from water 5, oil 6 and a surfactant 7, and introduced into a pipe line before the mixing tank 10, into a pipe line before an ultrasonic irradiation tank 11, into a pipe line before an ultrasonic irradiation tank 11', and into an agitation type granulator 4. Fine powder and oil in a mixture obtd. in the mixing tank 10 are condensed in the ultrasonic irradiation tank 11 and fed to an ash-separating tank 13. A water slurry rich in the decomposed suspended ash is fed to the ultrasonic irradiation tank 11' and introduced together with gas into an ash-separating tank 13', where the slurry is divided into a slurry rich in condensates and a water slurry rich in ash. The latter is fed from the ultrasonic irradiation tank 11' to an ash-separating tank 13''. Then condensates separated in the separating tanks 13, 13', 13'' are granulated in the agitating granulator 4 and dehydrated by a dehydrator 9 to obtain the deashed coal.

Abstract: PURPOSE: To provide an acoustic transducer which is provided with single directional characteristic by increasing the acoustic wave output of one direction by an operating frequency and reducing the acoustic output of a reflection direction by the reflection means of the transducing and reflection means of the single layer constitution of a conductive material. CONSTITUTION: Other than the phase difference of π/2 between transmission waves and reflection waves, that is between A and B and between C and D, respective reflection strips 20 are offset for λ/8 to a position which is separated for the integral multiple of λ/2 from the center 31 or 32 of a finger group. Thus, the phase difference of 2×λ/8, that is λ/4, that is π/2, is generated between the transmission waves and the reflection waves which propagate in the same direction, that is between A and D and between B and C, further. The phase difference is added to the phase difference between sound waves, propagated in one direction and subtracted from the phase difference between the sound waves propagated in the other direction.  In this case, additional interference is present in one direction, destructive and offsetting interference is present in the other direction, and respective transducers indicate the single directional characteristics, that are unidirectional characteristic, corresponding to them.
